Wait while you make a good point that it fits in a wallet. Slightly less than half of the wallets don’t have a pocket to go into so need to go into a purse. While I have been known by my family and friends for having the smallest purses, the lanyard wins for me hands down! Guys have it so good. I never find clothes with pockets, I’m probably too cheap.
On the other hand, you can't fit much in pockets. Ladies get to carry more useful stuff in a purse. Plus, it's so much easier to sneak snacks into the movies...
